D&H 2595(NS) is a non-synthetic electrode depositing super duplex stainless steel weld metal. The weld metal exhibits high strength and resistance to stress corrosion cracking, pitting, and crevice corrosion. It is ideally suited for welding of super duplex stainless steels UNS S32550, S32750 and S32760 (wrought) and UNS J93370, J93380, J93404, CD4MCuN(cast) and similar compositions. Examples of application areas are: Oil and gas industry Oil country tubular Food processing Valves and fittings Flue gas de-sulfurizers Off shore plat forms Petrochemical plants Mechanical and structural components.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
2. The heat input should be in the range of 0.5-1.5 KJ/mm.
3. Please ensure inter pass temperature is less than 150 C and better less than 102 C.
4. For better results solution annealing at 1080-1120 C is required.
